How to Maintain Portal Crane Bearings

It is important for any overhead crane bearings to endure heavy radial loads and constant heat stress. Incorrect selection of materials and improper maintenance can lead to bearing products deteriorating. Also, rust and corrosion are potential hazards. Bearings must be cleaned and greased after use. Using the right anti-rust oil application method is also critical.

The first step is to choose the right cleaning and grease application methods. Some common types of cleaning include solvent cleaning, mechanical cleaning, and chemical treatment cleaning. Once the rust is eliminated, you can apply the appropriate anti-rust oil. If necessary, you can also dry the gantry crane bearings with filtered compressed air or cotton. Be careful not to damage the bearings while cleaning.

Another factor that can cause premature wheel bearing failure is excessive deflection of the crane. If the load is too heavy or the crane is not properly installed, the deflection can wear out the bearings. Similarly, if the rail systems are too flexible, the crane may experience extreme deflection. Moreover, a poor rail attachment can lead to bad rail support.

Finally, you can ensure the long-term reliability of your crane by using superior quality bearings. These can help your crane keep functioning at a high level. There are different types of crane bearings, such as rolling bearings, sliding bearings, and single-row four-point contact ball series. Rolling and sliding bearings have different shapes and sizes, and rolling bearings are generally more expensive. You can select the type of bearing that best suits your specific needs.

The main functions of a bearing are to provide stability for the rotating mechanical body and to reduce friction during the movement. Rolling and sliding bearings have higher vibration and noise, and they are divided into various series. Sliding bearings are usually used to operate in applications that require less axial force. However, they can also be used in applications that involve extreme axial and radial forces. Lily is one of the world's leading bearing manufacturers, and they offer a wide variety of standard slewing bearings and can design custom slewing drives to meet your specific requirements.

The spring return is a device on the master switch. Normally, it is attached to a fixed structure, such as a floor level. During operation, it limits the motion of the crane bridge in an upward direction. It is also used to limit the travel of the trolley.

As you can see, a rust-free gantry crane requires proper cleaning and grease application. When cleaning the gantry crane, make sure you choose the correct anti-rust oil application method and use it carefully. Moreover, the bearings should be thoroughly dried after they are cleaned and greased. Anti-rust oil should be applied based on the rated load. After that, the gantry crane should be inspected and checked. If it is found that the bearings are damaged, you can replace them.

Crane bearings are a vital component of the lifting process, and you can avoid inefficiency and unnecessary downtime by choosing a high-quality product.
